szl boiler brown coal fired 8 ton steam boiler
The transformation of low nitrogen boiler should be noted that what matters for retrofitting low nitrogen boiler should be noted that what? Of nitrogen oxide emissions is large, complex sources, environmental problems caused by acid deposition, fine particles, ozone, nitrogen oxides and analysis of contamination status must be further strengthened. If you do not take further measures to reduce emissions, with the United States and the United States to speed up economic development, population growth and urbanization, nitrogen oxide emissions will continue to grow in China in the future. Based on current trends, by 2030, emissions will reach 35.4x106 tonnes, will inevitably cause serious environmental impacts. Therefore, we must effectively enhance the emission control of nitrogen oxides. From this we can see that low nitrogen boiler is imperative! A check device to check for low NOX combustion gas before commissioning is in place, the gas pipeline flow is clean, whether the valve is open. There is a burner pipe leaks, reasonable pipeline installation. Discharging vent pipe valve from the foregoing, to ensure that no mixing of the air duct, and the exhaust pipe should be connected to the outdoor. Second, stable combustion and combustion of homeostasis Remember, combustion adjustment is the basis for all of the low nitrogen burner adjustment, as long as guaranteed under any changes in operating conditions of combustion stability and combustion of dynamic equilibrium, to burn steam temperature influence is even greater. Since the steam temperature is a sign flue gas heat value balance between the steam and heat absorption, this can be maintained as long as the dynamic balance, steam temperature can be kept stable. Third, the level of flame boiler boiler central flame center is also an important factor in high impact low-temperature steam. In the high temperature steam operation, the amount of coal combustor exhaust can be reduced, the amount of the lower stage burner of coal may be increased, and vice versa. Running low nitrogen burners, it should also be noted effect of different combinations of temperature steam mill. Steam at a low temperature exhaust composition regulating a large margin, the combination of the high temperature exhaust temperature adjusting stage so small margin overheat. It should be strengthened and soot blowing air distribution according to the situation.
Check Item item hot water boiler hot water boiler comprising a boiler inspection and checking internal use preparations, checking in the furnace and the flue, the boiler attachment check, check automatic control system, the secondary device, check the combustion device, the auxiliary heat check the surface of the hot water boiler must be done before running some tests, these tests are quite a lot of us, it is possible because of our neglect and causing very serious consequences. Therefore, we must forestall, be sure to carefully check the following before the hot water boiler operation. 1, including the use of internal inspection and boiler ready. 2, inspection, and furnace fouling and debris inside the flue in the furnace and flue should be cleaned. Flue duct and damper, the shutter must be complete and compact, flexible switch, opening and closing accurately indicated. 3, check the boiler accessories, check the safety accessory is intact; cock is rotating flexible, easy to use; all kinds of instruments and controls should be complete, good, clean. After passing the examination, should the gauge cocks in working condition. 4, check the automatic control system. 5. Check the accessory device. 6, inspection of the combustion apparatus, the combustion apparatus is intact inspection; mechanical transmission system, coal handling system, the ballast system test switch normally; spring-loaded safety level of a gearbox should be appropriate, well lubricated; coal shutter indicate the correct scale. iron eagle neat, well, turn the ballast plates full, flexible movement. 7, the auxiliary heating surface of the inspection, check the auxiliary device (fan, blower, pump, etc.) are firmly connected coupling; proper belt tension triangle; oil should be good enough; cooling water flow. After passing the examination, installed security guard, respectively, commissioning, and note the current when idling. It is fed out of the hot water boiler heat equivalent to a mass per hour (usually expressed in tons) in water was heated from 20 ℃ and heat output of all vaporized into a szl boiler brown coal fired 8 ton steam boiler water absorbed three expressions, in tons) water from 20 ℃ heated and vaporized into all heat absorbed by the steam boiler it is fed out of the hot water heat equivalent to a mass per hour (i.e. typically kcal / hr (kcal / h), tonnes / hour (t / h ), megawatt (MW). (1) kcal / h is in metric units of expression, which represents the heat of hot water boiler fed out per hour. (2) t t borrowed steamed steam boiler popular argument, ( 3) megawatts (MW) is the international system of units unit of power, the basic unit is W (1MW = 106W). this expression formal documents should be used.
June 20 this year, Changji Hui Autonomous Prefecture in Xinjiang Uygur Hutubi County textile industrial park a LOHAS fruit and vegetable plant in the region, two workers were dismantling a height of 20 tons of steam coal-fired boiler chimney 50 meters, which is Finally, the county removed a large tonnage of coal-fired boiler, after the removal of 300 tons per year to reduce coal pollution.
After removal of coal-fired boilers, textile industrial park will access a unified steam heating system, the coal-fired boiler plant will be dismantled access system, both low nitrogen environmentally friendly and energy efficient.
In recent years, Hutubi County to respond positively to China's environmental protection policy, and vigorously promote the "Blue Sky Project", to conduct a comprehensive environmental management and air pollution control activities that will improve air quality as the top priority of economic and social development.
It is understood that Hutubi County this year to increase environmental protection efforts, the New Chemical Materials Park, Textile Park, a new industrial park and other parks coal-fired boilers are dismantled processing equipment, present the industrial park has been demolished 67 companies a total of 98 fuel stations coal boiler, after the removal of 10,000 tons per year to reduce coal pollution.
Secretary Hutubi County Industrial Park Administrative Committee of Economic Development, Sun Xiaotong said: "Industrial Park to good project access, the introduction of new projects, environmental protection must first over that hurdle; increase the park's environmental infrastructure investment , to lay the foundation for entry into the project; increase the industrial enterprises of environmental remediation efforts, requires companies to complete the task of environmental protection standards, to achieve green development, restructuring and development, quality development. "
April 6 this year, Hutubi County has also set tough fight pollution prevention and control headquarters, hand drawn increasing ecological environmental issues reform efforts, strict implementation of environmental protection, "A Pair of responsibility," "party and government with responsibility" layer by layer progressive pressure tight compaction tasks to ensure that environmental issues rectification precise place.
Deputy Director of Hutubi County Office of Pollution Prevention battle command room Zhangxin Hao said: "conscientiously implement the idea of ecological civilization Xi Jinping, the CPC Central Committee and implement the spirit of ecological protection zone state Assembly to do the rectification work to promote the co-ordination of environmental protection issues, and resolutely fight tough fight pollution prevention efforts to build a sky blue green water of the Qing Hutubi. "
ZG Boiler can supply oil & gas fired szl boiler brown coal fired 8 ton steam boiler, coal fired steam boiler, biomass fired steam boiler, CFB steam boiler, waste heat steam boiler to paper mill. However, biomass fired steam boiler is the most suitable one for paper mill.
